Reaction Steps

A solution of 3,6-dichloro-N-(3,4-dimethoxybenzyl)pyridazine-4-carboxamide (1-2, 0.100 g, 0.292 mmol, 1.0 equiv), 3,3-dimethylphenylboronic acid (0.053 g, 0.351 mmol, 1.2 equiv), Cs2CO3 (0.238 g, 0.731 mmol, 2.5 equiv) and PdCl2(dppf) (0.043 g, 0.058 mmol, 0.2 equiv) was made in dioxane (2.0 mL) and heated to 80° C. for 2 hours. The reaction mixture was cooled and partitioned between EtOAc and water. The organic phase was dried over MgSO4 and concentrated. The residue was purified by normal phase column chromatography (0 to 85% EtOAc in hexanes) to afford the product (1-3) as a solid. ESI+MS [M+H]+ C22H22ClN3O3: 412.1 found, 412.1 required.
